So what, you ask, does the Holy Father agree with scientists on? Actually, now that you mention it, it's hard to tell.

Seems
scientists tested some material taken from what Catholic tradition
holds is the tomb of St. Paul, one of Jesus's disciples. What they
found, CNN reports the pope as saying, is that bones in the sample "belong to someone who lived in the first or second century."

And, therefore.....?

"This seems to confirm the unanimous and undisputed tradition that
these are the mortal remains of the Apostle St. Paul," Benedict said in
Sunday's announcement.

Let's follow the logic here:

1) Bones are in an ancient sarcophagus that is, traditionally, believed to be St. Paul's tomb.

2) Church tradition also holds that Paul was beheaded in either the year 65 or the year 67 CE.

3) The bones are tested and found to date to "the first or second century," or somewhere between 1 and 200 CE.

4) No one but St. Paul lived during that period. Ignore the theory
suggesting that Jesus and 11 other disciples (plus a few folks that
Jesus guy encountered) were alive somewhere around then.

5) The next reported human appeared after 200 CE. Ignore the theory that suggests others must have lived then.
